What it does

Hackernews Publisher is an agent skill from eunomia-bpf/eunomia.dev. Prepare or publish Hacker News submissions and follow-up drafts for eunomia.dev content, GitHub projects, papers, demos, and Show HN style launches. Use when asked to submit, adapt, publish, QA, or record HN posts. Covers original-source selection, title normalization, curiosity-first positioning, browser duplicate checks, publication authorization, comment follow-up, and media ledger updates.

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `agents/openai.yaml` and `references/platform-preferences.md`).

It sits in Marketing & SEO, covering Database schema design. It works with GitHub. The repository describes itself as: https://github.com/eunomia-bpf homepage, documents and blogs. The licence is MIT.

Read from SKILL.md and the folder at commit 4cc0b4f. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.

Network

From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hackernews Publisher loads about 827 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 104 tokens; SKILL.md has 388 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~104
When it runs · the whole SKILL.md, loaded when a task matches: ~827
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Hacker News Publisher

Prepare Hacker News submissions. Publication authorization follows CLAUDE.md's Precedence Rule and Publishing section.

Inputs

Source URL, GitHub repo, paper, demo, blog post, or topic.
Submission type when specified: regular link, Show HN, Ask HN, or comment.
Optional title, text, or follow-up plan.

If the source URL is missing, inspect recent docs/blog/posts/, relevant GitHub repos, and canonical eunomia.dev URLs before asking the user.

Platform Entry Points

Submit: https://news.ycombinator.com/submit
Show HN: https://news.ycombinator.com/show
New: https://news.ycombinator.com/newest
Search: https://hn.algolia.com/

Use a browser surface with the logged-in session when UI work is required.

References

Load references/platform-preferences.md when choosing HN fit, title, source URL, Show HN eligibility, browser checks, promotion balance, or comment follow-up. Do not load broad strategy drafts for routine submissions unless the user asks for campaign or content-platform planning.

Browser-Only Platform Boundary

Do not use unofficial submission automation, internal endpoints, or vote-related actions. All checks and submission prep must come from normal browser interactions.

Draft Preparation

Decide whether HN is appropriate for the item.
Prefer the original source: GitHub repo, paper, demo, or canonical article.
For an existing long-form source, preserve the original title exactly except for a platform-required marker such as [pdf]. A different title requires explicit user instruction.
Use Show HN only for something readers can try.
Do not write generated comments for direct posting; draft comment options for user review and ownership.

Show full SKILL.md (159 more words)Show less

Draft Archive

Before opening the HN submit page or comment box, write or update the HN draft under draft/media/YYYY-MM-DD/<source-slug>/hackernews.md using the local date. Include submission type, title, URL, duplicate-check state, Show HN eligibility, and any full paste-ready comment options for user review.

Browser QA

the same URL/topic is not already active
title is neutral, not all-caps, and does not include the site name
URL is the original/canonical source
Show HN title is only used when the artifact is tryable
the final action matches the task: submitted when authorized, untouched for a draft-only task

Follow-Up

After confirmed submission, capture the HN item URL. Monitor comments only when the user asks or follow-up was part of the task. Draft concise, human-reviewed technical replies. Do not solicit upvotes or comments, and do not ask others to submit or promote the link.

Ledger Update

After confirmed submission, update .github/publisher/media/published.md with source path or URL, HN URL, date, submission type, title, and follow-up notes.
